Textbooks, books for libraries and lab notebooks are typically Smyth Sewn because they stand up to years of wear and tear. Smyth Sewn bindings use thread to sew through folded signatures of a book. Signatures are made by printing on large sheets and then folding into groups of pages, usually 16 or 24 at a time. Each signature is sewn individually with threads going through each page several times. The threads are then tied off. All of the signatures are likewise attached together with thread creating what is called the book block. The book block is further strengthened using flannel and adhesive on the spine.
